Thread: Horten 229 FPV

    Flapudders Instead Of Flaperons

    My next stage in building my Horten 229 is to install the Drag Rudders.
    I will try to make a simple hinged spoiler system.
    What I would like to try out is a mix of Flaps and Rudder ("Flapudders ") instead of mixing Flaps with Ailerons (" Flaperons").
    It will be a bit of a challenge to program the reversing of steering during full speed brakes on.

    Nice work canadianstarman, i'm def subbing to this build.
    I to am working on something like this, but then for a teksumo wing (monkey blunt version).
    I also will be implementing decelerons (drag rudders) but they will also function as the ailerons, elevators and air-brake's all with only a 4 servo double elevon setup.
    It's something I was experimenting with last year and finally figured out how to do it last week.
    Here's my wiring and programming setup:

    Now I'm trying to get it to work with a CC3D in the equation to also get a stabilized version.
    I have also just heard that it should be possible to only use the CC3D and that i could ditch the V-tail mixers, but this is a hole different ball game in programming the CC3D for me so it's going to take me awhile to get it going.

    Hope this might help you a bit, and good luck with your build!

    Regards

    That's great to hear that your working on the same setup.
    I just finished building a prototype of my drag rudder.
    Your idea of using a CC3D board sounds like the way to go.

    http://www.openpilot.org/product/coptercontrol/.

    Here's some pictures of my latest progress of my drag rudder prototype.
    My next step is to develop the controller , so this is good timing to get some ideas
    from somebody else.

    Thanks T !

    Looking good! but why use 2 servo's when you can doe the same with 1 servo?

    I found this vid on YT with a simple nice mechanism. Might be something for you?



    And check this thread over on that other forum other idea's:

    I checked out the 1 servo mechanism (that you referred to) awhile ago and I actually bought the parts to build it but I abandoned the build for the following reasons:
    - I want to be able to independently adjust or modify the throw and throw rates of
    lower and upper control surfaces.
    - I want to minimize adjusting the linkage mechanism and make most of the
    adjustments with software.
    - I want lots of torque available for each control surface.
    - I want redundancy so that if one servo goes bad then I can still be able fly.

    Referring to the following thread the dimensions of the lower control surfaces are
    different than the upper.
    http://www.rcgroups.com/forums/showt...1731896&page=2

    I plan on starting off with scale drag rudder control surfaces and then modify them
    ( if necessary ) to get best flight performance.
    Should be interesting to see how the design settles into.

    Test Flight Controller Design

    Before I install all my FPV gear, I will install a special drag rudder controller that will
    help in figuring out the proper throws for the drag rudder control surfaces.


    I will use a servo and 2 limit switches to switch rudder signals from port servos to starboard
    servos.




    I designed a simple servo travel limiter circuit to be able to individually adjust travel of each of the 4 servos.




    A relay will be used to switch from drag rudder mode to Air Brake/ Rudder (or what I call Flapudder) mode.

    Horten 229 X-plane Flight Simulator

    I've used X-plane flight simulator software to try out different P.I.D. parameters
    on my Skywalker FPV and I now want to use the flight simulator to try out
    flying a simulation of the Horten 229.

    I found it interesting in the following video how the elevators set during take off.
    Something to consider on my maiden flight.
    The builders of this simulation have programmed functional drag rudders.
    So this simulator will hopefully help me get some drag rudder flying experience.

    Still Working On Drag Rudder Design

    I got The Horten 229 X-plane flight simulator downloaded and got a handle on drag rudder flying. The beginning of the video, the drag rudder mechanism near the wing tip can be seen.

    I decided to change my drag rudder mechanism.
    I hot glued a quick prototype of my design.
    Still lots of room for improvement and hope to get it in its final design on my next
    build period.
